After four grueling years at the Virginia Military Institute, upon graduation as an engineer, I decided to follow my own prudent path: I would find the best paying job in an area with the lowest cost of living that afforded me training opportunities. I knew myself well enough that I didn’t want to be stuck behind a desk; I desired interpersonal contact. I always aspired to be an engineering leader — and felt consulting would be the best route to that end.

July 1, 2022

All hydronic systems designed around renewable energy heat sources — as well as those designed around conventional boilers — have at least one controller that measures and responds to temperature. Common examples are temperature setpoint controllers, outdoor reset controllers, mixing controllers and differential temperature controllers. Complex systems that operate in multiple modes, or use multiple heat sources, often have several temperature-based controllers.
